Multiscale and multimodality in-situ probing of structural and chemical evolution of energy storage materials
EMSL Project ID
48688
Abstract
The main objective of the proposed research is to develop and use a combination of ex situ, in situ, and dynamic TEM imaging and spectroscopy combined with STXM and x-ray tomography method to probe into the structural and chemical evolution of energy storage materials with atomic spatial and fast temporal resolution, to determine the structure-property relationship and its correlation with charge and ion transport in energy materials. In particular, we propose to use these chemical imaging methods to explore the new chemistry and nanostructured materials, such as Li-S and Li-air, for energy storage with high capacity, high power, longer cyclability and safe operation.
